Have you guys heard anything about the episode 23 lasting 2 hours?

I can't remember where... but I read something about it. It said the last episode would be 1 hour longer.
In some tv shows, like Lost and Grey's Anatomy, for instance, this is very common.
So what do you know about that? Or what do you think?

I havent heard anything about the season finale being a 2 hour episode yet, but last night greys anatomy was on for 2 hrs and theres still 2 more episodes left in the season. That would be a cool show if its 2 hrs, you always feel like a 1 hour heores goes really fast and isnt anaywhere near long enough!
